ALBERT H. yGILMAN, OF `HOPEDALE, MASSACHUSETTS. Leiters .Patent No. 72,285, dated December l'i', 1867.

vIlldlllOll-IMENEI IN LUBRIGATING SPINDLES.

TO ALL PERSONS TO WHOM THESE PRESENTS MAY COMEL Be it known thatliv-.ALBERI H. G-ILMAN, of Hop'eda-le, inthe county .of Worcester, andState of Massachu- Betts, have made a new and useful Invention havingReference to Machinery for Spinning Roving; and do hereby i declarethe'same to be fully described iu the following specification, andrepresented in the accompanying draw- Figurel is a side elevation, and vFigure 2 a vertical section cfa spindlefbolster andbobbin-rotator orgear, containing my invention.

Figure 3 is a horizontal section of the bolster. l I v In such drawings,A denotes a spindlerextending through a bolsterB, and provided with abevel-gear, C, for e'ecting rotary motion'oi sfuch spindle.` .Abrassbushing or tube, D, goes through the bols'tennnd projects bothabove and below it, in'manner-asrepresented in fig. 2. A small screw, a,is cnt on thevlou'er part of the lsaid bushing for thepurposeofreceiving an annular nut, E, which is constructed with a femalescrew, b, to fit the screw a. The said nut encompasses the` spindle, andAis formed with an annular chamber, c, arranged so as to encircle thespindle and open against it. Within such chamber is a studing, d, offelt, woollen, cloth, or other suitable absorbent, the Purpose of vwhichis to catch and retain oil which may run down the Spindle, and toreapply such oil to the spindle during its vertical and rotary motionsrelatively 4to the bolster. lIhe bolster I form with a lateral chamber,e, which should open into or communicate with the spindle 'by a slot,f,formed vertically through the bushing. i This chamber I prefer to .makein an extension, g, ofthe bolster. The cham ber is open at top, andis tocontain a stuing or tube, h, of-fclt or other proper absorbent material,which is to extend from the chamber e. through the slotf, and againstthe spindle. By pouring oilinto the mouth of the chamber e, andsaturating the absorbent material contained therein, we shall have ameans of effectually lubrieating the spindle, the surplus oil beingcaught bythe stung of the chamber c. The bobbin-rotator orgear is shownlat F as encompassing-the upper parts of the bushing and resting on thetop ofthe bolster. .An-annular chamber, t', is formed in and around thebore or eye of the said bolster, and there is a hole or passage, t,Vleading upward from such chamber to the top, of the rotator. Withinthesaid chamber is a stuffing or annulus,

l, of felt or other suitable absorbent material, which is designed toholdoil when poured upon it through the passage c, the object being tolubricate that part of the b'ushing'on which the bobbin-gear is placed.

From the above, it will Vbe 4seen that we have a ready meansoflubricating those surfaces ofgthc bushing l against which the spindleand the bobbin-gear vor rotator may revolve.

By making thechamber e open at top, itwill catch the surplus oil thatmay escape from the bearing of thel gear F, or the upper part ofthebushing, and will lead such oil againstthe spindle.

I claim the combination of the chamber-ed nut E, provided with anabsorbent material, as set forth, with the bolster, or with the sameandthe bushing, to extend down from such bolster, as explained. e

I also claim the combination of the chambered nut E, provided with anabsorbent, as -set forth, with the bolster and its chamber e, furnishedwith an absorbent material, arranged so as to lie against the spindle,as `speciied. i

Ialso claim the combination of tbechambered nut E, the chambered bolsterand bushing, provided with a, passage and an 'absorbent material .toextend-through'such passage and against the spindle, as described.

I also claim the combination of the lubricating-chamber z' and itssupply-passage 7c with the gear F, the bearing thereof, and the conduite,'or its equivalent, arranged in the bolster and to open against thespindle, as

i specified.
